"Developer options" is hidden by default. To make it visible, please go to "Settings" -> "About phone" and tap "Build number" a couple of times. Return to the previous screen to find "Developer options". And then click on the checkbox for "USB debugging" to turn it on.

Note: While you connect your phone to your PC via USB cable, if you get "Connect storage to PC",do not click.

Aside from thiking that my Samsung usb plug isn't working, I noticed that when I plug the USB wire to PC and then do the debugging mode, there is no recognized device attache to it. What problem could it be? Previously it works perfectly.

We had to purchase a new computer. Previously Mobisynapse operated pretty much ok on VISTA HP. New computer is HP with Windows 8. I installed MOBISYNAPSE and mOffice on new HP. However, after many attempts the computer and my Atrix phone will not sync. We are attempting to obtain solution to the problem, or to switch the entire operation, calendar, contacts, etc., to a completely new program.

I am running windows 8 and office 365 with outlook. i was able to sync up to a couple of weeks ago. i have deleted your programs and reinstalled on both pc and my samsung galaxy 4 and i am still not able to sync the pc and phone. HELPPPPPPPPPPPPPPPPP
